Si Nan was born with a chaotic body, but was sealed by the rootless thunder and became a useless person. Ten years later, the divine thunder came again, and the chaotic body awakened. Only then did he realize that he could practice without the Dantian. The stronger the thunder tribulation he survived, the more powerful he gained. From then on, he embarked on a road that used lightning tribulation as a ladder to blast through the walls of the heavens and lead directly to the supreme summit.
